LABEL-WIPING MACHINE.

Application filed August 2, 1916.

To all whom it may concern:

Be it known that we, JOHN EMANUEL Jonnson and CHARLES H. OSLUND, citizens of the United States, both residing at WVorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Label-Wiping Machine, of which the following is a specification.

This invention relates to a wiping device constituting part of a labeling machine, and involves improvements over the several kinds of wiping devices shown in our prior Letters Patent on a rotary labeling machine, patented Aug. 28, 1917, No. 1,238,713.

The principal objects of this inventlon are to provide an improved arrangement of wipers suited for wiping a label around a conical bottle neck, so as to lay the ends of the label down on the bottle in slanting position; to provide improved means whereby thelabel will be entirely wiped around the bottle; to provide a new and improved order of wiping operations, and to provide 1m provements in the details and arrangements of parts.

Reference is to be had to the accompanying drawings in which- Figure 1 is an elevation of a preferred embodiment of this invention, showing the hottle supporting table in cross section;

Fig. 12 is a central sectional view on the line 1212 of Fig. 11, and

Fig. 13 is a horizontal sectional view on the line 13-13 of Fig. 11.

As in our above identified patent, we have shown this invention as applied to the labeling of a bottle A carried by a carrier as, for example, a rotary table 10 on which it rests. It is to be understood that before the operation of the mechanism shown herein commenced to take place the bottle on this table, as indicated in Fig. 4, is provided with a body label B and a neck label C which are held against the bottle by a gripper 127, the construction and operation of which are not shown herein as it does not constitute part of this invention. The wiping mechanism, as in the above identified case, is carried by a stationary vertical rod 131 on which is adjustably fixed a bracket 132 provided with an arch 133 under which the bottle A is adapted to pass. We have also shown a pair of stationary rubber wipers 14:6 carried by this arch for wiping the body label on the bottle as shown in Fig. 10. No claim for that is made herein as it is shown in full in the above identified case.

The neck label wiping mechanism is operated by a shaft 10 which receives power from any desired source, and is provided with a double faced cam 11. One of the cam grooves thereof operates a lever 12 which, by means of a link 13 extending upwardly, oscillates a lever 14 pivoted freely on a horizontal stationary rod 15, carried by the arch 133. At the other end this lever 14 has a fork 16 which engages a pin 17 on an arm 18 loosely pivoted on a horizontal stationary rod l9-also carried by the arch. Integrally connected with this arm 18 is another arm 20 so that the two constitute a bell crank. At the lower end this arm 20 is provided with a pin 21 which engages a slide 22 working on an inclined guide 23 on the arch. This guide is provided with a slot 24 along which the pin moves, and the slide 22 has a wiper 25 on the end adjustably fixed thereon, and adapted to be reciprocated in an inclined path by the action of the parts just described. There is a vertical slot 26 for receiving the pin 21 to permit of a straight line motion on the part of the slide, although caused by an arcuate motion on the part of the arm 20.

The other half of the cam 11 operates a lever 27 which is connected by a link 28 with one arm 29 of a bell crank which is pivoted loosely on the shaft 15. The other arm 30 of this bell crank is connected with a slide 32 having a wiper 35 thereon by mechanism similar to that described in connection with the slide 22.

The two rods 15 and 19 carry two depending hubs 38 from which extend rods 39. On each of these rods is adjustably mounted a hub 41 which carries a projecting arm 12. To this, by means of a screw 43, is secured a plate 44 to which is adjustably connected a wiper 45. The two wipers 15 extend in from opposite sides, and although they do not move during the operation of wiping, they are adjustable out and in, also adjustable to any desired angle about the screws 43 and to any desired angle about the rods 39, on which they are also vertically adjustable.

In the operation of wiping the bottle con tinuously moves in the direction indicated by the arrow in Fig. 1 so that the neck thereof first passes between the wipers 45, as indicated in Fig. 5. This wipes the neck label on into a position in which its two ends project backwardly from the neck substantially parallel with each other. The bottle then advances and engages the wiper 25, as indicated in Fig. 6. This wiper is c then moved in by the cam to the position inthis operation that the body label engages,

dicated in Fig. 7 at which time it will be seen that the label is forced against the neck of the bottle clear to its end. As the bottle moves on and this wiper is withdrawn, it engages the wiper 35 which is drawn back and then moves in again to the position shown in Fig. 9, thus wiping the other end of the label around into position. In this way a label can be applied extending entirely around the bottle neck. It is during the wipers 146, as indicated in Fig. 10, and is secured in position in the manner set forth in the above identified application.

From what has been said it will be seen that improvements are provided over the mechanism shown in said application as far as the neck label is concerned for the following reasons. In the first place, the label is laid smoothly and centrally in position by the advance wipers 45 which do not have to be given any motion, but can be adjusted to lay the label primarily in any desired position. This is an important feature because neck labels are used having widely different shapes, sizes and locations. The wiper 25 for laying out one end of the label is caused to complete its operation before the last neck wiper 35 really commences to operate. Furthermore these two wipers 25 and 35 move on an inclination which is a desirable feature when a bottle neck of conical form is being labeled, because it gives the label the right slant at its ends and permits the wiping of the extreme edges thereof.

In Figs. 11, 12 and 13 we have shown a modification of the neck wiping device designed for similar purposes. In this case the parts 131, 132 and 133 are the same as above described and the arch 133 is provided, as in Figs. 25 to 28 of our above identified patent, with a reciprocating archshaped frame 134 which is operated by a lever 141 connected by a link 143 with a cam or other means for operating it. Guides 135 are shown for guiding this frame. At the bottom the frame is provided with feet 149 having slanting rear surfaces on which the wipers 150 are located. In this way it will be seen that the wipers move downwardly with a rectilinear motion, and that they are located at an inclination so thatthey perform a wiping operation suitable for wiping the ends of a label placed on the bottle neck in such position that its ends slant. This is usually the case with the neck label for a bottle having a conical surface.

. Although we have illustrated and described only two forms of the invention, we are aware of the fact that other modifications can be made therein without departing from the scope of the invention as eX- pressed in the claims. Therefore we do not wish to be limited to all the details of construction herein shown and described, but what we do claim is 1. In a label wiping device, the combinastantially completed its operation and capable of lapping that end of the label over the other end thereof.

2. In a label wiping device, the combination of a pair of stationary wipers for preliminarily smoothing out a label, a third wiper arranged back of one of the first named wipers, means for reciprocating the third wiper in its own plane, a fourth wiper arranged back of the other of the first pair of wipers and at a distancebeyond the third wiper, and means for reciprocating the fourth wiper.

3. In a label wiping device, the combination of a pair of wipers for smoothing out a label, means whereby said wipers can be adjusted longitudinally, transversely and angularly, and additional wipers for completing the wiping operation.

4;. In a label wiping device, the combination of a pair of preliminary wipers, and a wiper adapted to act on the same label thereafter, the last named wiper being reciprocable toward and from the article being labeled at an inclination.

5. In a label wiping device, the combination of a pair of preliminary wipers located in position for engaging the end portions of the label and smoothing it out, with another wiper having its operating surface arranged in a plane substantially parallel with that of the preliminary wipers adapted to engage one end of the label thereafter at a point operated upon by one of the first named wipers, and means for moving the last named wiper inwardly in the direction of its own plane.

6. In a label wiping device, the combination with a frame, an inclined guide on the frame, a wiper adapted to reciprocate along said guide, and means on the frame for reciprocating said wiper.

7. In a label wiping device, the combination of an arch-shaped frame, a pair of guides located on opposite sides of said frame, one of them a material distance behind the other, said guides being located in slightlyinclined position, wipers movably mounted on said guides, and means on the frame for reciprocating the. wipers.

8. In a label wiping device, the combination of a frame, a pair of wipers located one forward of the other on the frame and both reciprocable toward the center of the frame, a pair of swinging arms connected with said wipers, whereby the oscillation of said arms will reciprocate the wipers, and means for oscillating said arms.

9. In a wiping device, the combination of a frame, a pair of stationary rods located thereon parallel with each other, a bell crank on each rod, a pair of wipers below the rods,

one connected with each bell crank to be reciprocated thereby, a pair of rods depending from the first named rods, and wipers adjustably mounted on the last pair of rods.

10. In a label wiping device, the combination of a frame, a pair of inclined wipers .movably carried thereby, and means for moving said wipers toward the center of the frame in the general direction of their inclination.

11. In a label wiping device for applying a label to th curved surface of an article while in constant motion forwardly, the combination of a pair of stationary wipers oppositely located and overlapping each other for engaging the center of the label as the article passes between them and wiping it on around substantially half of the article, and a wiper located in position to be engaged by the label as the article continues to move forward and movable transversely to operate first on the label at the side of the article where one of the first wipers engaged it and then move inwardly and wipe the end of the label around on the rear side of the article.

12. In a label wiping device, the combination of a carrier, means for holding an article on the carrier in fixed position, a label gripper, and a wiper for locating and preliminarily smoothing out the label on said article, with a laterally movable fiat wiper arranged in position to move in behind the article in its own plane and engage the label throughout its own motion and to operate on one extreme end of the label at a point there of previously engaged by the stationary wiper and to paste it to the rear of the article after the stationary wiper has completed its operation and While the article to be labeled faces in the same direction.

In testimony whereof we have hereunto aflixed our signatures.
